Ground Finch (Geospiza fortis) A male medium ground finch (Geospiza fortis) feeds on fruit from a Scutia spicata thorn shrub, Santa Cruz Island, Galapagos. Geospiza fortis is one of "Darwin's finches" which he derived much of his theory of evolution from observations he made of the species during the 1831 to 1836 voyage of the H.M.S Beagle.
